Mac配置Flutter环境变量

打开终端，输入命令 open ~/.bash_profile，会打开一个bash_profile文件窗口，加上下面配置：

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
export FLUTTER=/Users/shushi/flutter-sdk/flutter/bin
export PATH=FLUTTER
export PATH="/usr/local/opt/libxml2/bin:$PATH"

其中 export FLUTTER=/Users/shuuhiroshi/flutter-sdk/flutter/bin，为flutter的sdk目录中bin的路径。
ctrl+s保存没关闭
在终端输入source ~/.bash_profile
配置完毕
输入flutter -version，检查配置是否成功
